1.2 ABOut vOltAge-sensing teChnOlOgy
The voltage-sensing wire feeder uses the welding voltage to generate the energy required for
controlling the wire feeder’s operations. Before starting to weld, you just select the desired
settings for the feeder and the power source according to the welding requirements, the base
and filler material, and the shielding gas to be used.
When you start welding in CC mode, the feeder controls the parameters so that the quality of
the welds always remains high.
In normal MIG/MAG welding, the parameters’ values are controlled by the power source via
the control cable, but voltage-sensing technology makes such a control cable between the
power source and the feeder unnecessary.
Constant Current (CC) power sources
The CC type of welding machine changes the wire feed speed according to the arc voltage.
The voltage will change with different arc lengths while only slightly varying the amperage.
Constant voltage (Cv) power sources
The CV type of welding machine maintains a relatively stable, consistent voltage regardless of
the amperage. It results in a relatively flat volt-amp curve. The MIG/MAG welding machines are
typically CV type machines.
